PathsD offset generate additional unexpected paths

[F-Fede]

Hi,

I stumbled across another strange situation: I have two paths I try and offset, I expect just a single merged inflated result, but I get three results (that seems to be the expected one plus two noisy ones).
I think I'm calling the method with enough precision (actually, I tested different values, from 2 [default] to 8).

I call the method as Clipper.InflatePaths(subj, delta, JoinType.Round, EndType.Polygon, precision: 6), and I obtain a result as in the following picture.

For completeness sake, I attach a file with the full path to recreate the result.
As usual, thanks for any kind of feedback! :)

Noted. I'm investigating 😁.

This line should be
if (cosA > 0.999)

[F-Fede]

I'll check and let you know ASAP ;)

Hi Angus,

the case is resolved! :)

Unfortunately, something after that seems still to have have issues... I'll dig deeper into that and check if it is Clipper2 related: in case, I'll keep you posted on this thread (otherwise I will close as resolved).

[AngusJohnson]

Yep, there is another minor bug in the C# code here. It should be...
else if (cosA > 0.99 || _joinType == JoinType.Square)

[F-Fede]

Yeah, that improve the situation!
The specific offset operation worked; unfortunately, it was a starting operation of a chain of offset, and I still have some problems.
However, I will investigate further and keep you updated!

I'll give that a try, thank you!
